Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to an independent water storage tank and a dental comprehensive treatment table. Background Art

[0002] The dental chair is used for oral surgery and examination and treatment of oral diseases. Its base plate is fixed to the ground and connected to the upper part of the dental chair through a bracket. The movement of the dental chair is controlled by the control switch on the chair back. In actual application, according to the needs of treatment, the control switch button is operated, and the dental chair can complete the actions of rising, falling, tilting, supine position and resetting, so as to better serve oral surgery.

[0003] At present, the side box of the dental chair is generally equipped with a water supply system. The water supply system is connected to a water bottle, and the other end of the water supply system is connected to each dental handpiece, so as to supply water to each dental handpiece. The traditional water supply system can only be connected to one water bottle. Before daily use, the dental handpiece and the water supply pipeline need to be disinfected. The specific method is to unscrew the water bottle, pour in the disinfectant and then put it back in the water bottle, and then turn on the water supply system to start pumping water, so that the disinfectant flows through each dental handpiece for disinfection. After a period of disinfection, unscrew the water bottle again, pour in pure water, continue to pump water, and use pure water to rinse the residual disinfectant in the pipeline to complete the disinfection operation.

[0004] Obviously, the above steps require disassembling and assembling the water purification bottle back and forth, which is very troublesome. Therefore, in the prior art, some dental chairs are also equipped with two water purification bottles. For example, the utility model patent with publication number CN215460448U proposes a dental chair disinfection system, which has two water bottles, and the two water bottles are respectively filled with disinfectant and pure water, and the water supply system is connected to the two water bottles respectively. When disinfection is required, the water supply system can be used to pump out disinfectant and pure water in turn, so there is no need to disassemble and assemble the water bottle back and forth, which greatly simplifies the disinfection steps. In order to achieve the above-mentioned technical effect of not having to disassemble and assemble the water bottle back and forth, and to distinguish it from the above-mentioned two-bottle disinfection system, the present invention proposes an independent water storage tank and a comprehensive dental treatment table.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figure 2 — Fig.11 An independent water storage tank includes a tank body 100 and a liquid pumping mechanism 200, wherein a first cavity 101 and a second cavity 102 are provided inside the tank body 100, and two liquid outlets 103 are provided on the top of the tank body 100, and the two liquid outlets 103 are respectively communicated with the first cavity 101 and the second cavity 102; the two cavities are not communicated with each other, and the first cavity 101 and the second cavity 102 are used to contain disinfectant and pure water respectively.

[0039] like Fig.11 As shown, the outer sleeve of the liquid outlet 103 is provided with a liquid outlet cap 104, the top surface of the liquid outlet cap 104 is provided with a liquid outlet pipe 105, the bottom surface of the liquid outlet cap 104 is provided with a water suction hose 106 connected to the liquid outlet pipe 105, and the side of the liquid outlet cap 104 is also provided with an air hole 107; wherein, the water suction hose 106 is located in the corresponding cavity for pumping water, and the air hole 107 is used to maintain the pressure in the cavity consistent with the external atmospheric pressure.

[0040] Furthermore, the liquid extraction mechanism 200 includes a liquid extraction box 201, which is detachably connected to the top of the tank body 100. A liquid extraction cylinder 202 is disposed inside the liquid extraction box 201, and a first water pipe 203 and a second water pipe 204 are disposed on both sides of the liquid extraction cylinder 202. Figure 7 As shown, the first water pipe 203 and the second water pipe 204 are respectively connected to the two liquid outlets 103, and the first water pipe 203 and the second water pipe 204 are both provided with solenoid valves; specifically, the free ends of the first water pipe 203 and the second water pipe 204 both penetrate the bottom wall of the liquid extraction box 201 and extend to the outside of the liquid extraction box 201, and the inner surfaces of the two liquid outlet pipes 105 are provided with sealing rings. When the first water pipe 203 and the second water pipe 204 are respectively inserted into the two liquid outlet pipes 105, the sealing rings are tightly fitted to the outer surfaces of the first water pipe 203 and the second water pipe 204 to prevent air leakage.

[0041] In addition, the bottom surface of the liquid extraction box 201 is provided with a buckle 205, such as Figure 2 As shown, the top surface of the tank body 100 is provided with a clamping portion 206 adapted to the buckle 205, and the buckle 205 is clamped and matched with the clamping portion 206. Therefore, the liquid extraction box 201 and the tank body 100 are detachably connected, and are easy to disassemble and assemble.

[0042] In one embodiment of the present application, the liquid pumping cylinder 202 is a cylindrical structure, and a displacement portion 207 is movably provided inside the liquid pumping cylinder 202, and a piston ring 208 is fixedly provided on the outer side of the bottom of the displacement portion 207. Figure 5 As shown, a spiral blade 209 is provided on the outer side of the displacement portion 207 and above the piston ring 208, and the piston ring 208 and the spiral blade 209 are both in contact with the inner surface of the liquid extraction cylinder 202; specifically, notches 210 are symmetrically provided on both sides of the piston ring 208, and blocking pieces 211 are provided in the two notches 210, and the blocking pieces 211 movably penetrate the side walls of the displacement portion 207, and the displacement portion 207 is a hollow structure. The inner ends of the two blocking pieces 211 are hingedly provided with connecting rods 212, and the free ends of the two connecting rods 212 are jointly hingedly provided with lifting pieces 213; when the lifting piece 213 moves up and down, it can indirectly drive the two blocking pieces 211 to move forward and backward. It should be noted that the shape of the blocking piece 211 is consistent with the notch 210. When the outer end of the blocking piece 211 is in contact with the inner surface of the liquid extraction cylinder 202, the piston ring 208 can divide the internal space of the liquid extraction cylinder 202 into two.

[0043] In this embodiment, a lifting component for controlling the lifting piece 213 to move up and down is further disposed inside the displacement portion 207 . The lifting component is introduced below.

[0044] The lifting assembly includes a vertical rod 214, such as Fig.10As shown, one end of the vertical rod 214 is fixedly connected to the inner bottom wall of the displacement part 207, and the vertical rod 214 movably passes through the lifting piece 213. A return spring 215 is sleeved on the outer side of the bottom of the vertical rod 214. The two ends of the return spring 215 are respectively in contact with the lifting piece 213 and the inner bottom surface of the displacement part 207. When the two blocking pieces 211 are in contact with the inner surface of the liquid extraction cylinder 202, the return spring 215 is in a compressed state. A lifting sleeve 216 is also sleeved on the outside of the vertical rod 214 and located above the lifting plate 213. A round hole is opened on the top of the displacement portion 207 for the lifting sleeve 216 to extend out. A first magnetic block 217 is provided on the inner top surface of the lifting sleeve 216. An electromagnet 218 is provided on the top of the vertical rod 214. When the electromagnet 218 is energized, the facing magnetic poles of the electromagnet 218 and the first magnetic block 217 are the same; when the electromagnet 218 is de-energized, the electromagnet 218 and the first magnetic block 217 attract each other, the bottom end of the lifting sleeve 216 abuts against the lifting plate 213, and the two blocking plates 211 abut against the inner surface of the liquid extraction cylinder 202.

[0045] Specifically, when the electromagnet 218 is powered on, the magnetic poles of the electromagnet 218 and the first magnetic block 217 facing each other are connected, so the lifting sleeve 216 moves upward under the action of repulsion, and the lifting sleeve 216 does not contact the lifting sheet 213. Under the elastic force of the return spring 215, the lifting sheet 213 rises, and the two blocking sheets 211 shrink inward to expose the gap 210; when the electromagnet 218 is powered off, the first magnetic block 217 and the electromagnet 218 attract each other, so the lifting sleeve 216 moves downward and presses the lifting sheet 213 downward, so that the two blocking sheets 211 move outward and abut against the inner surface of the liquid extraction cylinder 202.

[0046] In this embodiment, the liquid pumping cylinder 202 is also provided with a driving component for driving the displacement portion 207 to rotate or move up and down. The driving component is introduced below.

[0047] The drive assembly includes a drive motor 219 and a drive ring 220. Fig. 9As shown, the drive motor 219 is fixedly installed on the top surface of the liquid extraction cylinder 202, the output shaft of the drive motor 219 extends into the liquid extraction cylinder 202 and is provided with a drive disk 221, the drive ring 220 is sleeved on the outer side of the displacement portion 207, the drive ring 220 and the drive disk 221 are fixedly connected by a support rod 222, the inner surface of the drive ring 220 is provided with a drive column 223, the outer surface of the displacement portion 207 is provided with a closed drive groove 224 along a circumferential circle, and the drive column 223 is embedded in the drive groove 224; the drive groove 224 is a two-section structure composed of a first spiral segment 2241 and a second spiral segment 2242, the first spiral segment 2241 is counterclockwise upward spiral, the second spiral segment 2242 is clockwise upward spiral, the first spiral segment 2241 and the second spiral segment 2242 are connected end to end to form a closed groove body, and the length of the first spiral segment 2241 is greater than the second spiral segment 2242.

[0048] Specifically in this embodiment, the number of turns of the first spiral segment 2241 is three quarters of a turn, and the number of turns of the second spiral segment 2242 is one quarter of a turn. Figure 5 In addition, the top surface of the lifting sleeve 216 is provided with a straight-line anti-skid protrusion 225, and the lower surface of the driving disk 221 is provided with an anti-skid groove 226 adapted to the anti-skid protrusion 225. When the anti-skid protrusion 225 is embedded in the anti-skid groove 226, the driving disk 221 can drive the displacement part 207 to rotate synchronously.

[0049] On the other hand, the side wall of the liquid suction cylinder 202 is provided with a vertically distributed guide groove 227, and the side wall of the displacement portion 207 is movably penetrated by a guide column 228, and the inner end of the guide column 228 is provided with a second magnetic block 229, and the outer surface of the lifting sleeve 216 is provided with a third magnetic block 230 and a fourth magnetic block 231 distributed up and down, and the third magnetic block 230 and the second magnetic block 229 have the same magnetic poles at the opposite ends, and the fourth magnetic block 231 and the second magnetic block 229 have opposite magnetic poles at the opposite ends; when the electromagnet 218 is powered off, the third magnetic block 230 is opposite to the second magnetic block 229, and when the electromagnet 218 is powered on, the top surface of the lifting sleeve 216 abuts against the drive disk 221, and the fourth magnetic block 231 is opposite to the second magnetic block 229. Therefore, when the electromagnet 218 is powered off, due to the repulsive force between the second magnetic block 229 and the third magnetic block 230 , the guide post 228 will extend outward until the outer end of the guide post 228 and the inner surface of the lifting sleeve 216 abut against each other.

[0050] It should be noted that when the electromagnet 218 is powered off and the drive motor 219 controls the drive ring 220 to rotate, the drive column 223 will also drive the displacement part 207 to rotate due to a certain friction between the drive column 223 and the drive groove 224, until the outer end of the guide column 228 is embedded in the guide groove 227, and the displacement part 207 cannot rotate. At this time, the displacement part 207 can be driven to reciprocate up and down under the rotation of the drive ring 220. It is worth mentioning that the drive ring 220 rotates clockwise, and when the drive column 223 is inside the first spiral section 2241, the displacement part 207 moves upward, and when the drive column 223 is inside the second spiral section 2242, the displacement part moves downward, and because the second spiral section 2242 is steeper than the first spiral section 2241, the descending speed of the displacement part 207 is greater than the ascending speed.

[0051] On the other hand, the bottom and top of the liquid pumping cylinder 202 are respectively provided with the third water pipe 232 and the fourth water pipe 233, the third water pipe 232 and the fourth water pipe 233 are both communicated with the inside of the liquid pumping cylinder 202, and the third water pipe 232 and the fourth water pipe 233 are both provided with electromagnetic valves, and the ends of the third water pipe 232 and the fourth water pipe 233 are connected with the fifth water pipe 234 through a three-way pipe. It should be noted that the electromagnetic valves on the first water pipe 203 and the third water pipe 232 are both one-way electromagnetic valves, specifically, when the one-way electromagnetic valve on the first water pipe 203 is opened, only water flow is allowed to enter the liquid pumping cylinder 202, and when the one-way electromagnetic valve on the third water pipe 232 is opened, only water flow is allowed to be discharged from the liquid pumping cylinder 202.

[0052] In summary, when it is necessary to extract disinfectant, only the electromagnetic valves on the first water pipe 203 and the third water pipe 232 are opened, and the electromagnet 218 is in a power-off state, and the drive motor 219 is turned on. In this state, the blocking piece 211 extends outward and abuts against the inner surface of the liquid pumping cylinder 202. With the operation of the drive motor 219, the displacement portion 207 is driven to move up and down, so that the disinfectant in the first cavity 101 is drawn into the liquid pumping cylinder 202, and then the disinfectant is discharged into the third water pipe 232, and reciprocates in sequence to achieve intermittent liquid supply. It is worth mentioning that the top wall of the liquid pumping cylinder 202 also has an exhaust valve, which only allows gas to pass through and cannot allow liquid to pass through. When the piston ring 208 moves up and down, the liquid pumping cylinder 202 can complete gas exchange with the outside world through the exhaust valve.

[0053] When pure water needs to be extracted, only the solenoid valves on the second water pipe 204 and the fourth water pipe 233 are opened, and the electromagnet 218 is energized, and the drive motor 219 is turned on. In this state, as the drive motor 219 works, the displacement part 207 is driven to rotate, and then under the action of the spiral blade 209, the pure water in the second cavity 102 is extracted into the liquid extraction cylinder 202, and then the pure water is discharged into the fourth water pipe 233, thereby realizing continuous liquid supply.

[0054] It is worth mentioning that the height of the guide groove 227 is greater than the maximum spacing between the displacement part 207 and the driving disk 221, which is greater than the height difference of the driving groove 224; in addition, when the electromagnet 218 is energized, the lifting sleeve 216 moves upward until the anti-slip protrusion 225 is in contact with the inner bottom surface of the driving disk 221. At this time, as the driving disk 221 rotates, relative rotation will occur between the driving disk 221 and the displacement part 207. When the anti-slip groove 226 is aligned with the anti-slip protrusion 225, under the repulsive force of the electromagnet 218, the anti-slip protrusion 225 can be embedded in the anti-slip groove 226 in time, and at this time the driving disk 221 can drive the displacement part 207 to rotate synchronously.

[0055] Embodiment 2: This embodiment of the application proposes a dental comprehensive treatment table, such as Figure 1 As shown, it includes the independent water storage tank in the first embodiment, and also includes a base 300, a seat 400, a foot switch 500, a side box 600 and a spittoon bowl 700, wherein a water supply pipeline is provided inside the side box 600, the water inlet end of the water supply pipeline is connected to the fifth water pipe 234, and the water outlet end of the water supply pipeline is connected to each dental handpiece. Specifically, the liquid extraction box 201 is always fixedly connected to the outside of the side box 600 in a natural state, and the tank body 100 is detachably connected to the bottom of the liquid extraction box 201, which is convenient for disassembly and replacement of water.

[0056] It should be noted that the side box 600 also has a power supply inside (not shown in the figure), and the solenoid valves on the first water pipe 203, the second water pipe 204, the third water pipe 232 and the fourth water pipe 233 are all electrically connected to the power supply, and the drive motor 219 and the electromagnet 218 are also electrically connected to the power supply. The side box 600 also has a controller outside for controlling the on and off of the above components.

[0057] In the specific application of this embodiment, when it is necessary to extract disinfectant to clean each dental handpiece, only the solenoid valves on the first water pipe 203 and the third water pipe 232 are opened, and the electromagnet 218 is turned off, and the drive motor 219 is turned on. In this state, the disinfectant enters the pipeline of each dental handpiece in an intermittent manner. On the premise of achieving disinfection, the bacteria or impurities attached to the pipeline can also be flushed away by flushing. After a period of disinfection, pure water is extracted to continue flushing to clean the residual disinfectant in the pipeline.

[0058] It is worth mentioning that due to the special shape of the driving groove 224, the displacement part 207 rises slowly and falls quickly when performing up and down reciprocating motion. The advantage of this design is that it increases the flow rate of the disinfectant during flushing, thereby increasing the impact force, further removing the residual dirt in the pipeline, and improving the cleaning effect.
